Jaguars Notebook: Harvey hungry for first sack

"Jacksonville's defense has got to show up and put some pressure on the quarterback," Sapp said. "Derrick Harvey, let's go baby."

Harvey is still looking for his first NFL sack, but the Jaguars' pass rush is a team problem. They only have five in the first four games and rank 27th in sacks per pass attempt.

Harvey, who probably was singled out by Sapp because the former University of Florida standout was the eighth overall draft pick, said he doesn't feel any pressure.

"All I've got to do is go out there and work hard every day," Harvey said.

The Pittsburgh Steelers might be the perfect opponent for a rookie seeking his first sack as the team has allowed 16 this season. The Jaguars also had 11 sacks in two games against the Steelers last season.

"That makes you a little bit more hungry and more excited to play them," Harvey said of the Steelers' problems protecting star quarterback Ben Roethlisberger.

Harvey made his first start last Sunday against the Houston Texans and didn't have a sack or a tackle, but he was credited with a quarterback hit.

The Jaguars' second-round pick, Quentin Groves, has a sack, but he came up empty against the Texans.

"I have to be patient and know it's going to come to me," Groves said.

Groves wants to emulate Tennessee Titans defensive end Kyle Vanden Bosch, who's known for his work ethic.

"His motor never stops," Groves said. "I have to have two or three moves for every guy."

Secondary still hurting

The Jaguars might be thin in the secondary Sunday night against the Steelers. Two starters - safety Reggie Nelson and cornerback Drayton Florence - didn't practice for the second consecutive day.

Nelson missed the victory over the Texans because of a bruised knee that hasn't healed. Florence suffered a groin injury in the final defensive series against Houston, and he said there's a chance he'll play, but he isn't sure if he can.

The condition of both players will be updated today.

The Jaguars' other starting cornerback, Rashean Mathis, was limited in practice for the second consecutive day after bruising a shin in the first half against Houston.
